There is a huge amount of variation in different animal species, and thus each species may need specific medicines for the same disease. Hence, the research and marketing of veterinary medicines is more complicated as compared to human medicines. Unlike human medicines, there is no regulation in the prices of veterinary medicines. The selection of veterinary medicines accounts for more than 270 trade names. The worldwide Veterinary Vaccines market ($4.23 Bn) accounted for approximately 20% of the total Vaccines market ($29.71 Bn) in 2010. It has been estimated to grow with a CAGR of 5.80% to reach the market size of $5.6 Bn by 2016.
